Ok. I've just about exploded my brain trying to figure this out.
For about the last month, when I run the airconditioning compressor in my KR, the main radiator fan comes on, instead of the auxilliary fan. I've traced all the wiring back as far as I can go, and all the fuses and fusible links are intact.
The thing is, when I connect the auxilliary fan to a 12V source, ie. the battery, it runs. When I switch the blower and compressor on, which, under normal conditions, would cause the auxilliary fan to run, and check the fan plug terminals with a multimeter, there's barely any voltage reading.
What could be causing the main fan to come on in place of the auxilliary fan?
